CI/CD

Answer-first: Large monoliths avoid slow CI/CD pipelines by implementing monorepo path-filtering, Go build caching, and selective test execution based on git diffs. Deploying a single-binary modular monolith enables atomic deployments where application code and schema migrations ship deterministically in a single commit release. Prerequisite: Before reading this part, please review Part 3: DDD Module Boundaries. What You’ll Learn: Go Build Tags & Bazel Caching: How to isolate integration tests and share Go compilation objects across CI runners. Sub-3-Minute CI Blueprint: How git diff path filtering and worker pools compress test pipeline execution times. Internal Interface Contract Testing: How to verify cross-module Go interfaces without external network mocks. Automated Kamal 2 / ECS Deployments: How single-container releases execute atomic database migrations safely before traffic cutover. One of the biggest drivers pushing teams toward Microservices is the promise of “Independent Deployment.” In theory, team A can deploy service A without caring about team B. But reality is often much crueler: The existence of “Dependency Hell.” ...

Prerequisite: Familiarity with the concepts introduced in Part 3 — Ai Bug Taxonomy. Review it first if the terminology in this part is unfamiliar. Part 4 — Multi-Agent Review Pipeline Architecture Answer-first: Operating a single-prompt AI code reviewer leads to context saturation and missed security vulnerabilities. A Multi-Agent Review Pipeline dispatches specialized sub-agents (Security Auditor, Performance Inspector, Syntax Linter) concurrently in Go to evaluate incoming pull requests in parallel, returning consolidated architectural code reviews in under 45 seconds. ...

Prerequisite: Familiarity with the concepts introduced in Part 9 — Agentic Observability Monitoring. Review it first if the terminology in this part is unfamiliar. Part 10 — Production Evals & CI/CD Guardrails: LLM-as-a-Judge at Scale In traditional software development, continuous integration (CI) relies on deterministic unit and integration tests. A function either returns the expected string or it fails the build. In GenAI and RAG engineering, responses are non-deterministic. A minor adjustment to a system prompt, a change in vector embedding models, or an update to chunking strategy can silently degrade response quality, introducing subtle hallucinations or dropping key context facts. ...

Prerequisite: Familiarity with the concepts introduced in Part 3 — The 10X Productivity Reality. Review it first if the terminology in this part is unfamiliar. Answer-first: The traditional software development lifecycle (SDLC)—characterized by strict wall-separated handoffs between Business Analysts, Developers, QA Testers, and DevOps Engineers—is obsolete. AI automation collapses these boundaries into a unified Quality Control (QC) feedback loop where developers execute real-time AI test generation, security scanning, and infrastructure synthesis during active coding. ...
